Descriptions

The Fibre Channel driver for QLogic adapters in IBM AIX 6.1 and 7.1 does not properly handle DMA resource limitations, which allows local users to cause a denial of service (system hang) via vectors that generate a large amount of DMA I/O, related to a deadlock in timer processing across CPUs.

El controlador "Fibre Channel" para adaptadores QLogic de IBM AIX 6.1 y 7.1 no maneja apropiadamente las limitaciones de recursos DMA, lo que permite a usuarios locales provocar una denegación de servicio (cuelgue del sistema) a través de vectores que generan un gran número de I/O DMA, relacionado con un deadlock en el procesamiento de un temporizador a través de CPUs.
